Undocumented Query Parameters You Can Use With Letterbird URLS

Example URL: https://letterbird.co/melanie

Using every parameter in the example URL: https://letterbird.co/melanie?name=from&email=email&body=body&subject=subject&hideheader=1

  • hideheader=1 - hides the header and profile picture
  • name= - Pre-fills the from name field
  • email= - Pre-fills the from email field
  • body= - Pre-fills the body text area
  • subject= - Pre-fills the subject field if enabled

As always with query parameters, you should probably run the strings you want to use as the value through encodeURIComponent() so that things like spaces become %20, newlines become %0A, and @ symbols become %40.

Of note, sometimes Letterbird will try to store some of these values in localStorage to hold on to what the user has inputted manually and it will overwrite the query parameters.
